First of all, please don't tell me to just......use the search thing on forums. Or plugin section. I've done it already but unsuccesfully.
What I need is, hide old posts of my blog from a certain fixed date. And by hide, I mean make em completely disappear from category countings,archives, front page, rss, etc.
It's ok if I can just hide a whole category, I'll just move old posts into a brand new cat i'll make. I tried all "hide categories" plugins but no one worked.
I have no problems altering template files and such, but I'd avoid to work on the core, since I cron svn up each night.
So....any help please ? :D
